Is this the ghost of Lee Harvey Oswald?

My friend was recently in Dallas and went to The Sixth Floor Museum at Dealey Plaza. While outside, he snapped some photos of the Texas School Book Depository from the street. If you look closely at the window where Lee Harvey Oswald allegedly assassinated President Kennedy from, there looks to be a person in the window. If you have been on this tour, you know that this corner is sealed off by glass from the public and nothing has been set in front of the window by museum staff. Notice the figure in the window appears to be wearing a white t-shirt and is crouching while looking out.

Could this be the ghost of Lee Harvey Oswald?

Note: Photos were taken on an iPhone from the North side of Elm Street and the South side of Elm Street. This is close to where Kennedy was hit with the fatal shot(s) to the head.
